2019-08-20nb/via/vx900: Ensure memory size and base are in rangeJacob Garber
We need to ensure uma_memory_size and uma_memory_base stay within a 32-bit address range. Both of these variables are 64 bits wide, so it is simplest to use 64 bit math when doing the bit shifts and then check if they are in range after.

2019-08-20nb/amd/pi,sb/amd/sr5650: Remove unnecessary allocationJacob Garber
add_ivrs_device_entries() is a recursive function, and each recursive call is passed a pointer to a root_level variable declared outside the function. In an attempt to make the function self-contained, the initial call is made with the root_level pointer set to NULL, and then the function attempts to detect this and allocate a root_level variable for the rest of the calls. This makes memory management very tricky - for example, the pi code incorrectly attempts to free the root_level variable at the end of *each* recursive call, which only avoids being a double-free because free() in coreboot is currently a no-op. Let's keep life simple and declare root_level as a local variable outside the first function call instead.

2019-08-20src: Remove variable length arraysJacob Garber
Variable length arrays were a feature added in C99 that allows the length of an array to be determined at runtime. Eg. int sum(size_t n) { int arr[n]; ... } This adds a small amount of runtime overhead, but is also very dangerous, since it allows use of an unlimited amount of stack memory, potentially leading to stack overflow. This is only worsened in coreboot, which often has very little stack space to begin with. Citing concerns like this, all instances of VLA's were recently removed from the Linux kernel. In the immortal words of Linus Torvalds [0], AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and much _slower_ code (and more fragile code), than just using a fixed key size would have done. [...] Anyway, some of these are definitely easy to just fix, and using VLA's is actively bad not just for security worries, but simply because VLA's are a really horribly bad idea in general in the kernel. This patch follows suit and zaps all VLA's in coreboot. Some of the existing VLA's are accidental ones, and all but one can be replaced with small fixed-size buffers. The single tricky exception is in the SPI controller interface, which will require a rewrite of old drivers to remove [1].

The speed argument should be one of the six values from the mem_clock enum, so something is very wrong if this is not the case. Better to die now than return 0, which will cause a division-by-zero error later on where this function is called. The first two speeds are also unsupported and have the same problem with returning 0, so die on those as well.

2019-07-17nb/intel/nehalem: Prevent out of bounds readJacob Garber
If the decoded SPD DRAM frequency is slower than the controller minimum, then there will be an unsigned integer underflow in the following loop, which will lead to a very large out of bounds array access. Ensure this does not happen.
